ABSTRACT
Ammonia pressure leaching has been investigated as an alternative for hydrometallurgical processing of Lubin middlings – a shale-enriched flotation by-product. The effect of primary parameters: tem- perature, oxygen partial pressure, ammonia and ammonium sulfate concentration and stirring rate on leaching recovery of Cu, Ag, Zn, Ni, and Co were examined.
